In the first part of the dissertation, a third-order self-oscillating PWM class-D amplifier for audio applications, that utilizes a hysteretic comparator is described. The design is analyzed and its THD is theoretically determined by employing an equivalent model, that relates the approach to natural sampling pulse-width modulation.

audio band. 3. MODULATION SCHEME In this design to achieve filter free class D operation, a double-sided natural sampling pulse width modulation scheme is used. The distortion produced when using natural sampling consists of combinational components only at frequencies given by w c – nw v with n even. There are two main advantages of this
